Subject: Re: Glass, Stained Glass Painting

The title of the book I have is: _Stained Glass Painting: _Basic
Techniques of the craft_ Anita & Symour Isenberg and Richard Millard,
Radnor, Pennsylvania, Shlton book Company, 1979.

 Chapter 2: The Nature of Glass Paintmakes a distinction between window
glass and the glass used to make stained glass windows. This book covers
paint that is fired and that becomes part of the glass. Non-fired paints
are available, but their use is limited to window glasss, or small
graphic effects on stained glass. p. 11 - "Creativity with them is also
limited since they utilize a piece of glass as a canvas, and they do not
enhance the inherent qualities of the medium. No stained glass painter
uses non-fired paints for any lasting work, though they are fun to fool
around with. Their effect is transitory, especially compared to the
fired paints which can last for centuries."

 Further down: "Glass paint is composed of two substances, the vehicle
and the coloring agent. the vehicle is glass. It is made the same way
that glass is made, but with certain modifications. it is composed of
red or white lead ozide, sand boric acid, clay, alumina, sodium, and
potassium - all originally in powder form. This basix substance is
variable in content. some vehicles hav e a higher lead content, which
makes for a softer (lower firing) glass. A lower lead content makes the
vehicle harder (higher firing). all these powders are mixed together and
poured into a clay crucible which is then heated in a furance to about
1800F. The amount of heat is dependent on what type of color you will be
adding  to the vehicle. at 1800F this mass of powder melts, fuses, and
becomes a glass."

 For more information I would try to locate this book.
 Do not dispair about the "furnace". Contact Jewel at
jwainwright at taylorpub.com. She has a small table top kiln that gets up
to temperatures high enough to fuse sheets of glass together. It can
also be used to melt glazes on tiles. The components of the stained
glass paint sound like a glazes and vice versa. Jewel also has a lot of
experience doing stained glass and may have more information for you
about painting on stained glass and may have done this herself. The
e-mail is at her work place so keep your initial message short and ask
if she has time to help you. I hope that this gives you a lead on what
you are looking for. I would appreciate hearing back if either of my
messages has helped you in anyway. I have many interests, but not always
the time to follow up on them. How you get to do all of yours and will
look forward to applauding your results at some future event.
